YouTube/GoProThe world's most grueling high-speed endurance contest, the Tour de France, is about to get much more interesting for viewers after organizers announced Wednesday that on every stage at least eight bikes will be equipped with onboard cameras.

GoPro struck the deal with Tour organizer ASO and Velon, a group of 11 cycling teams "working together to grow and evolve through a growth in fan excitement and technology."

While most of the bike-cam footage will be edited and published after the stages, organizers said they'll be testing live images from the bikes on stage two during the neutral start.

"By mounting cameras to the fastest cyclists in the world as they take on the 21-stage race, GoPro will be capturing immersive, never-before-seen content, bringing cycling fans inside the peloton," GoPro said.

The race starts in the Netherlands on July 4 and finishes in Paris on July 26.

Here's how the bike cams should give us a new perspective on one of the biggest sporting events in the world.

While onboard cameras have been tested in races in the past, this year's Tour riders will be on camera in greater and more consistent numbers.

With onboard cams it's like climbing in the pack alongside the world's fittest athletes.

With a cam mounted on a rider's handlebar we get us a close-up look at the athlete's face, breathing, and reactions as he focuses on the wheel in front of him at between 20 and 70 miles an hour depending on terrain.

Normally we wouldn't get to see such close-up images of a guy hugging the side of the road like this as the bunch is ripping along.

From deep inside the peloton we get to see the nervous moments — such as rain-soaked riders fighting for position and quite literally rubbing elbows. There are effectively four riders in a space that would normally allow for just three.
